COMBINED DlTCHlNG-MACHINE, GRADER, AND LOADER.

SPECIFICATION forming part of Letters Patent No. 427,273, dated May 6, 1890.

Application filed January 14:, 1890. Serial No. 386,891. (No model.)

To all whom, it may concern:

Be it known that I, WILLIAM HENRY SAN- FORD, a citizen-of the United States, residing at Mountain Home, in the county of Baxter and State of Arkansas, have invented a new and useful Combined Ditching-Machine, Grader, and Loader, of which the followingis a specification.

This invention has relation to a combined road-plowing or ditching machine and dirt receiving and dumping car, the main object being to form a combined apparatus for the purposes above specified, which may be operated by convenient and economical means and without stopping the machine.

WVith these general objects in view the in vention consists in certain features of construction hereinafter specified, and particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a per- Fig. 2 is a trans- Fig. 3 is a vertiprojects inwardly considerably beyond the inner face of the wheel, forming a flange S,which is provided with a series of obliquely-disposed spikes 9. In recesses 10, formed in the end bars 2 and 3 and adjacent to the inner one of those longitudinal bars supporting the flanged wheel 6, is a sliding bar 11, from which depend opposite pairs of links 12, the lower ends of which support a vertically-adj ustable plow-beam 13, from which depends a plowstandard 14, carrying an ordinary turning plowshare 15.

16 represents a bracket projecting from the lower edge of the end bar 2 directly below the reciprocating bar 11, the end of which projects beyond its bearing, and pivoted at its lower nected with the forward end of the reciproeating bar 11.

19 represents an inclined table, from the ends of which project lateral trunnions 20, which take into bearings 21, formed upon the upper edges of the end bars 2 and 3. In this manner the table is pivoted within the frame. The upper edge of the table is cut away at its opposite ends, so that said ends terminate in close relation to the inner surface of the wheel. The lower edge of the inclined table rests in a longitudinal recess 23, formed in a rock-shaft 24, mounted in journals 25, formed upon the lower edges of the front and rear bars. The forward end of the rock-shaft projects beyond the end bar 2, and is provided with a lever 26, somewhat loosely mounted upon the shaft, adapted to be thrown to the opposite side of the stop-pin 27, and thus release the lower edge of the inclined table by removing the recess 23 of the rock-shaft from under the edge of the table.

28 represents the drivers seat, which is mounted upon a standard 29, projecting up wardly from the end bar 2, the lever 26 being within easy grasp of the occupant of the seat.

To operate the device, the team being started, the plow-operating lever is swung to the front, so that the plowshare is projected below the rim of the wheel 6. The dirt is thrown by the mold-board of the plow upon the flange 8 of the slowly-revolving wheel and carried by the spikes above the upper edge of the inclined table and dropped thereupon. When the table gets full, the plow is raised and the team driven to where the dirt is to be delivered. The lever 26 is then withdrawn'from behind the stop-pin 27 and the table permitted to swing downward and deliver the dirt without stopping the machine. After the dirt has been delivered the table is returned to its inclined position, and the rock-shaft is swung upward and secured by said pin and lever, and the operation may be repeated again and again.

Having described my inven tion,what I claim 1s 1. In a road-plowing machine, the combination, with the frame thereof and its support ing-wheel, of a reciprocating bar mounted in the frame, links depending from the bar, a plow-beam connec ed to the lower ends of the links, a plow-standard depending from the beam and provided with a share, and a lever pivoted to the reciprocating bar and having its lower end pivoted in a bearing below the bar, whereby by a reciprocation of the bar through the medium of the lever said beam and standard may be raised or lowered vertically, substantially as specified.

2. In a road-plowing machine, the combination, with the frame and a plow, of a wheel having a peripheral flange provided with dirtengaging teeth adapted to carry up the dirt received from the plow upon the flange, and a dirt-receptacle arranged at one side of the wheel and adapted to receive dirt therefrom,

substantially as specified.

3. In a road-plow, the combination, with the frame, a plow-standard depending therefrom, of a dumping-table and means for operating the same, and a wheel provided with an annular flange adapted to receive dirt from the plow and wit-h spikes for elevating the same and adapted to deliver said dirt upon thetable, substantially as specified.

4. In a road-plow, the combination,with the frame, of the rock-shaft mounted therein and having a longitudinal recess, a lever for operating said rock-shaft, and a pivoted table mounted in the frame and having its lower end supported within the recess of the rockshaft, substantially as specified.

5. The combination, with the frame, of a wheel journaled therein and provided with an annular inwardly disposed dirt elevating flange, of a table having trunnions journaled in the ends of the frame and having its upper edge cut away and extending under the upper portion of the flange of the wheel and its lower edge temporarily supported, substantially as specified.

WILLIAM HENRY SANFORD.
